A group of tabletop wargamers fight the Napoleonic battle of Austerlitz. At a crucial point in the action, you have to decide: left or
center?
The gamers are members of the Army Group York wargaming club in Pennsylvania, which produces the Little Wars TV channel. They post videos of wargame sessions, rules reviews, and miniatures tips†.
Austerlitz was the second iteration of their ‘choose your own adventure’ style wargame. In the first they teamed up with (against) the American Battlefield Trust on-site at Lee’s Headquarters to fight the Battle of Gettysburg. There were more options in that game but they were all made by polling ahead of time—except for one done live during the game—which limits the enjoyment for those tuning in afterwards (although the number of decisions voted on in advance gave some amusing order combinations.)
In their third outing they visited Brandywine Battlefield State Park where they were rejoined by the ABT to fight the eponymous battle of the American Revolution. This time they did early polling to determine initial strategy but, as with Austerlitz, they played through two versions of events allowing the viewer to decide: support or retreat?
